Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies (R)-Benzyl (1-(2-chloroacetyl)pyrrolidin-3-yl)(cyclopropyl)carbamate (CAS 1354019-63-8), a certified reference material (molecular formula C17H21ClN2O3, MW 336.81 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-Benzyl (1-(2-chloroacetyl)pyrrolidin-3-yl)(cyclopropyl)carbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), (R)-Benzyl (1-(2-chloroacetyl)pyrrolidin-3-yl)(cyclopropyl)carbamate 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.
