Analytical Reference Standard

Analytical reference standards are foundational materials for laboratory quality assurance, with applications spanning method development and validation, instrument calibration, system suitability testing, and result traceability in routine sample analysis. Whether deployed on chromatographic platforms such as HPLC, GC, and LC-MS/MS, or used in structural confirmation by NMR and IR, accurate and well-characterized reference standards are prerequisite for generating comparable, regulation-compliant analytical data. Under ISO/IEC 17025-accredited laboratory frameworks, traceability documentation — including a full Certificate of Analysis, value assignment methodology, and measurement uncertainty statement — is a key focus area during accreditation assessments.

The catalog spans pharmaceutical, natural product, environmental, food additive, and industrial chemistry applications, serving QC departments in pharmaceutical companies, CRO and CMO organizations, third-party testing laboratories, government regulatory agencies, and academic research institutions. Product formats include single-component standards, mixed standard solutions, and custom-formulated preparations, accommodating analytical needs from trace-level screening to high-precision quantification.

CATO Research Chemicals Inc. offers over 130,900 analytical reference standards, making it one of the broadest-coverage suppliers in China. The company holds dual ISO 17034 accreditation from both CNAS and ANAB, with each product supplied with a full Certificate of Analysis including HPLC purity, LC-MS confirmation, and NMR data, along with measurement uncertainty evaluation. The majority of products are available from stock, with same-day domestic dispatch and international delivery via FedEx temperature-controlled logistics to more than 13 countries worldwide.
