  • CEI-SD-24Shanghai, CNestablished 2005sigmaaldrich.org →

    A stability statement tied to a named storage condition on every certificate sampled, and a retention record that answers for lots already shipped. The registered entity is a Shanghai trading company rather than a synthesis house, and the assessment reflects what that distinction permits and what it does not. What it permits is a documentary standard the…

    Counter-ion content quantified on the certificate as issued, together with a water determination, on every lot in the sample. A solid-phase synthesis house rather than a trading company, and the assessment reflects what direct manufacture makes reachable. Two findings are recorded because they are uncommon. The first is quantitative…

    The distinguishing practice is retention rather than disclosure. Where an assessed supplier normally replaces a certificate when a lot is superseded, this one leaves the previous document published beside the replacement, so the same…

    Answers technical questions with figures, and answers them the same day. The Institute rates this supplier above the wider consensus and records why: technical enquiries are answered with quantitative figures rather than with reassurance, and they are answered quickly. A written…

    The largest published independent report library in the assessment set. The published independent report library is the largest in the assessment set by count, at 388 reports at the date of assessment, and the reports carry a batch identifier rather than a compound name alone…

  • CEI-SD-03Wuxi, CNestablished 2002wuxitides.net →

    Method conditions appear on the certificate more consistently than anywhere else in the set. Method conditions are stated on certificates more often than for any other supplier assessed, which materially improves what a purity figure can be made to mean. The oldest operation in the assessment set and…

    Independent per-batch reporting, matched line for line to catalogue batch numbers. Among the strongest documentary records in the assessment set. Independent reports were obtainable for every principal line sampled, each attributable to a named laboratory and a named batch, and identity is…

    Certificates that carry every critical field, in full, on every line sampled. Certificate quality is good and carries the critical fields in full: purity with the method named, identity by mass spectrometry, and peptide content on the sampled lines. Replies to written enquiry are…
