Assay vs Purity in 7-KLCA: Why Both Numbers Matter
Two percentage figures appear side by side on a 7-KLCA certificate and neither replaces the other. They differ in what sits in the denominator, and therefore in what each one...

No Method on the COA: What to Ask Before You Ac...
A number is only as usable as the method behind it. When a certificate reports content without naming the method, the figure cannot be compared with your own result.

Assay Above 100%: Why It Happens and When It Is...
An assay of 100.4% looks like a mistake and usually is not. The number is a ratio, and once you know what sits in the denominator the arithmetic stops being...

UDCA Solubility: Why the Profile Line Shapes Yo...
The solubility line reads like a description and behaves like a constraint. Four descriptors decide which solvents and which crystallisation routes are open to you before a trial batch is...

One identification test proves less than it appears to. The three used here probe three different properties, and they sit together because each is blind to what the other two...

UDCA Melting Range: Why 200–204 °C Is a Narrow ...
Most buyers skim the melting range and argue about assay instead. That order is backwards. The interval tells you whether the solid in the drum is the solid the specification...
