LazyChem

LazyChem is a chemical reference database and laboratory tools platform built to help users identify compounds and assess related information. Its searchable index covers more than 101,000 compound and active pharmaceutical ingredient pages, with records that may include names, CAS numbers, formulas, molecular mass, structures, stereochemistry, identifiers, sources, and documented history. Information is presented consistently to support comparison, and relevant records link to sources such as PubChem and official regulatory materials.

The platform also offers tools for resolving chemical structures and identifiers, checking stereochemistry and possible N-nitroso features, and reviewing India regulatory status. Its calculators cover HPLC metrics, concentration and dilution, weighing corrections, and analytical limits. Separate workspaces support shipping compliance assessments across identity, transport, packaging, customs, export control, and hazards, with unsupported or missing evidence left unresolved. Additional services include a mutagenicity assessment for impurity structures based on ICH M7 and a sourcing request option. LazyChem also provides guidance on EU packaging rules for laboratories and states that it uses essential browser storage without advertising trackers.
