Description
CATO supplies Boron Trichloride - Methanol Reagent (5-10%) [for Esterification] (1mL×10) (CAS 36254-91-8), a certified reference material (molecular formula BCl3CH4O, MW 149.20 g/mol) for analytical method development and quality control.
Structurally, Boron Trichloride - Methanol Reagent (5-10%) [for Esterification] (1mL×10) (BCl3CH4O) contains a hydroxyl group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 149.20 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Boron Trichloride - Methanol Reagent (5-10%) [for Esterification] (1mL×10) 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.
