Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1-Dibromo-2-chloro-2-(diethoxymethyl)-cyclopropane.
CATO supplies 1,1-Dibromo-2-chloro-2-(diethoxymethyl)-cyclopropane (CAS 851900-13-5), a certified reference material (molecular formula C8H13Br2ClO2, MW 336.45 g/mol) for analytical method development and quality control.
Structurally, 1,1-Dibromo-2-chloro-2-(diethoxymethyl)-cyclopropane (C8H13Br2ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 336.45 g/mol, it falls into the moderately-high-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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
