# CHEMISTRY GRADUATE — SDS / CHEMICAL DATA VALIDATION ## PERFORMANCE-BASED PROJECT — [login to view URL] **[login to view URL]** is developing a large chemical information database containing chemical products, molecular data and **SDS Reference Cards**. Website: [login to view URL] We are looking for a person with a: **Bachelor's Degree or higher in Chemistry, Chemical Engineering, Pharmaceutical Sciences or a closely related chemical field.** Your role will be to **review, check and scientifically validate chemical data contained in our SDS Reference Cards.** This is NOT simple data entry. ## YOUR TASK You will review SDS cards and verify whether the chemical information is scientifically correct and consistent. Depending on the compound, you will check: * CAS number * chemical identity * chemical name / synonyms * molecular formula * molecular weight * structure / SMILES / InChI * GHS / CLP classification * hazard statements * precautionary statements * toxicological information * ecological information * physical and chemical properties * transport information * regulatory information * source references * consistency between different sections of the SDS You will compare the information against authoritative scientific and regulatory sources where appropriate. ## THE OBJECTIVE We want every reviewed SDS Reference Card to have a **documented scientific validation**. You are not expected to blindly approve information. If something is incorrect, incomplete, inconsistent or unsupported, you must: **IDENTIFY → FLAG → CORRECT / RECOMMEND CORRECTION → PROVIDE SOURCE** The objective is to create a reliable and traceable chemical information database. ## YOUR SCIENTIFIC AUTHORITY Your academic qualification and professional review are important to this project. We want users to know that our chemical data has been **reviewed by a qualified chemistry professional**, rather than generated and published without human verification. Where appropriate, the reviewed data may display an attribution such as: **“Reviewed / validated by a qualified chemistry professional.”** The exact wording will depend on the validation process and project requirements. ## PERFORMANCE-BASED WORK We are primarily interested in **verified results**, not hours worked. You will be paid according to the number of SDS cards successfully reviewed and validated according to our agreed quality standard. For example: **X USD per correctly reviewed SDS card.** Quality is more important than speed. Repeated errors, unsupported approvals or superficial reviews will not qualify as successful validation. ## FIRST STAGE We will begin with a small test batch. You will receive several SDS Reference Cards and will be asked to: 1. review the chemical data; 2. verify the information against reliable sources; 3. identify errors/inconsistencies; 4. document corrections; 5. provide source references; 6. approve the card only when the agreed validation criteria are satisfied. Successful completion of the test batch will determine whether we continue with a larger workload. ## IDEAL CANDIDATE We are particularly interested in candidates with: * Bachelor's Degree or higher in Chemistry; * experience with SDS / Safety Data Sheets; * knowledge of GHS / CLP; * understanding of chemical toxicology and hazard classification; * experience with chemical databases; * strong attention to detail; * ability to work independently; * ability to research authoritative scientific sources; * good written English. Experience with **REACH, ECHA, CLP, PubChem, NIST or similar chemical/regulatory sources** is a strong advantage. ## APPLICATION Please provide: 1. Your degree and field of study. 2. Your professional experience in chemistry. 3. Your experience with SDS / GHS / CLP. 4. Your experience validating chemical data. 5. How many SDS cards you could realistically review per day while maintaining high quality. 6. Your proposed **price per successfully validated SDS card**. 7. Examples of relevant previous work, if available. ### IMPORTANT We are looking for a **qualified chemistry professional who is willing to put their professional knowledge behind the quality of the review**. This is a **performance-based scientific validation project**. **Accuracy > speed. Scientific evidence > assumptions. Verified results > hours worked.** EXAMPLE: [login to view URL] We need your signature! Please provide your price for FULL review in given language please!

I hold a Bachelor's degree in Biochemistry and have solid experience reviewing chemical data and Safety Data Sheets. I am familiar with GHS/CLP classification, hazard statements, and regulatory frameworks such as REACH and ECHA. I routinely cross-check chemical identities, CAS numbers, molecular formulas, SMILES, InChI, and toxicological data against authoritative sources including PubChem, NIST, and official regulatory databases. I understand this is performance-based scientific validation, not data entry. My approach is methodical: I identify discrepancies, flag inconsistencies, correct errors, and document every change with proper source references. Quality and accuracy come before speed. I can realistically review and validate 8 to 10 SDS cards per day while maintaining the high standard your project demands. I propose $9 per successfully validated SDS card, with payment tied strictly to verified, accurate results. I am ready to begin with your test batch immediately and look forward to contributing to a reliable, traceable chemical database. Please let me know if you need any additional details or samples of my previous validation work.

Hello, I am Muhammad Javed, a chemical/process-oriented engineer with more than 10 years of experience in technical engineering, scientific documentation, and detailed data analysis. I have carefully studied your complete project requirements and understand that this is a performance-based scientific validation task where accuracy, traceability, and reliable source verification are more important than speed. I can systematically review SDS Reference Cards by checking chemical identity, CAS numbers, molecular formulas and weights, chemical structures, physical/chemical properties, hazard information, toxicological and ecological data, transport details, regulatory information, and consistency between SDS sections. Where discrepancies are identified, I will clearly document the issue, recommend the appropriate correction, and provide the supporting authoritative source rather than making unsupported assumptions. I am comfortable conducting structured technical research and cross-checking information against reliable scientific databases and references. I can follow your validation criteria precisely and maintain a consistent review format across the entire dataset. I would be happy to begin with your test batch so you can assess the quality and depth of my work before assigning a larger workload.
