Is 6-Methoxy-2-Methylamino-3-Aminopyridine HCl natural?

Mostly not. Synthetic aminopyridine hair-dye core is petrochemical; the two chloride counter-ions are natural mineral-derived mass.

How we scored it

Aminopyridine free base (155.2 Da, petrochemical) + 2 Cl- (70.90 Da, mineral, natural) → 70.90/226.10 = 0.31.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Manufactured by amination/methoxylation of a petrochemical pyridine precursor, isolated as the dihydrochloride salt. No natural route exists for the heterocyclic core.

In plain English

A synthetic hair-dye coupler used in oxidative hair-colour formulas to help develop specific shades.
