01
Start with product identity
The product name is the first point of reference, but names alone may not uniquely identify a research material. A catalogue page may also show a common name, peptide sequence, molecular formula, molecular weight or CAS number where that information is available and appropriate.
These identifiers serve different purposes. A sequence describes the order of amino-acid residues in a peptide, while a molecular formula describes elemental composition. A CAS number can help distinguish a defined substance, but it does not replace the need to check the complete specification and supporting documents.
02
Strength and purity are different measurements
Listed strength describes the nominal amount of material in the supplied container, such as 5 mg or 10 mg. Purity describes the proportion represented by the target material according to a stated analytical method. A strength value should not be read as a purity result, and a purity value should not be assumed to describe container fill quantity.
A purity statement is meaningful only when its source and status are clear. A supplier specification, a batch-specific analytical result and an independently reviewed result are not interchangeable. AminoWorks identifies supplier-provided specifications as such and does not present them as independently verified evidence.
03
Check physical form and handling status
The physical-form field describes how the material is supplied, for example as a lyophilised solid. This can affect laboratory receipt, storage planning, weighing, preparation and record keeping.
General catalogue guidance does not override a batch-specific record, safety information or an organisation's validated procedure. Laboratories should resolve any uncertainty before opening or preparing the material.
04
Read document status literally
Document status tells the reader whether supporting material is published, available on request or not currently available. It is not itself a quality result and should not be treated as proof that a particular test was performed.
Where a document is batch-specific, its product identifier and batch or lot reference should correspond to the material being assessed. A report for one batch should not be used as evidence for another batch.
05
A practical review sequence
A consistent review process makes catalogue comparisons clearer and reduces the chance of treating unlike fields as equivalent.
- Confirm the product name and any available identity fields.
- Check the listed strength and physical form.
- Separate supplier specifications from batch-specific results.
- Review document availability and request clarification where needed.
- Record the source and date of the information used by the laboratory.
