Description
As a certified reference material (CRM), Prop-2-yn-1-yl 3-bromo-4-((2-chlorobenzyl)oxy)benzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Prop-2-yn-1-yl 3-bromo-4-((2-chlorobenzyl)oxy)benzoate (CAS 1706440-78-9), molecular formula C17H12BrClO3 and molecular weight 379.63 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Prop-2-yn-1-yl 3-bromo-4-((2-chlorobenzyl)oxy)benzoate (C17H12BrClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 379.63 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
