- Target Audience: SDS Authors, Industrial Hygienists (CIH), Board-Certified Toxicologists (DABT), Environmental Health & Safety (EHS) Directors, Chemical Compliance Officers, Regulatory Affairs Specialists, Laboratory Managers.

## Core Capabilities & Domains

- **CAS RN Multi-Database Cross-Referencing**: Real-time cross-database lookup across NIH PubChem, European Chemicals Agency (ECHA REACH / CLP / SVHC), US EPA TSCA (Active/Inactive Inventory, Section 5 SNUR, Section 6 Risk Evaluation, PFAS 40 CFR Part 705), OSHA (Permissible Exposure Limits PEL-TWA, STEL, Ceiling), ACGIH (Threshold Limit Values TLV-TWA, TLV-STEL, BEI, Notations), NIOSH (REL, IDLH), California Proposition 65 (NSRL/MADL safe harbor limits), and IARC/NTP Carcinogenicity.
- **Safety Data Sheet (SDS) & Material Safety Data Sheet (MSDS) Authoring**: Standard 16-section GHS SDS creation, legacy MSDS-to-SDS conversions, OSHA HazCom 2012 / HazCom 2024 compliance, Canadian WHMIS 2015 alignment, and multilingual regulatory translations across 70+ languages.
- **Industrial Hygiene & Occupational Exposure Limits (OEL)**: Critical toxicological basis evaluation, airborne concentration limits, local exhaust ventilation (LEV) specifications, dermal notations (Skin, SEN, DSEN, RSEN), and biological exposure indices (BEI).
- **Toxicological Risk Assessment & AI Toxicologist**: Certified toxicological mechanism analysis (CYP450 metabolism, oxidative stress, cellular adducts, endocrine disruption), GHS hazard classification, signal words (DANGER, WARNING), hazard statements (H-codes), and precautionary statements (P-codes).
- **Batch Excel Surveillance & Watchlists**: Bulk processing of industrial spreadsheets (up to 400+ CAS numbers), automatic regulatory change detection, and email alert dispatch for SVHC updates, TSCA rule changes, and ACGIH Notice of Intended Changes (NIC).

## High-Volume Terminology & Synonyms

- **MSDS (Material Safety Data Sheet)**: Legacy chemical safety document format widely searched by EHS technicians, plant operators, and warehouse managers. The platform seamlessly maps historical MSDS searches to modern 16-section GHS Safety Data Sheets (SDS).
- **SDS Authoring / SDS Authors**: Professional service and software for creating legally certified, GHS-compliant 16-section Safety Data Sheets and chemical container labels.
- **Industrial Hygiene**: The science and practice of anticipating, recognizing, evaluating, and controlling workplace environmental hazards, chemical vapors, mists, dusts, and physical agents.
- **Toxicology**: The scientific study of adverse effects of chemical substances on living organisms, determining dose-response relationships, carcinogenicity (IARC Group 1, 2A, 2B), and target-organ systemic toxicity (STOT-SE, STOT-RE).
- **CAS Registry Number (CAS RN)**: Unique numerical identifier assigned by the Chemical Abstracts Service to every chemical substance described in open scientific literature.
