Sulfur agbajibụ ihe mgbagwoju anya heterocyclic molecules ma ọ bụ ngwakọta etolite site na agbaze ma ọ bụ na-esi ogige organic nwere amino ma ọ bụ nitro otu nwere Na-polysulphide na Sulphur.A na-akpọ agbaji sọlfọ ebe ọ bụ na ha niile nwere njikọ sọlfọ n'ime ụmụ irighiri ihe ha.

Sulfur e ji esiji ákwà na-acha nnọọ agba, mmiri a na-apụghị ịsachasị mmiri, a ga-agbanwekwa ya ka ọ bụrụ ụdị soluble soluble mmiri (lucoforms) tupu etinye ya na ihe akwa.A na-eme ntughari a site na ọgwụgwọ nwere ihe na-ebelata ihe dị ka itughari mmiri Na2S.Ebe ọ bụ na lucoform nke Sulfur dye bụ ihe dị mkpa na ihe cellulosic.Ha na-etinye obi gị dum na eriri elu.Mgbe ahụ, ha na-reconverted mbụ mmiri insoluble ụdị agba site ọxịdashọn.A na-eme oxidation a site na "ikuku" (ikuku ikuku) ma ọ bụ site na iji ihe na-emepụta ihe dị ka Na-dichromate (Na2Cr2O7).

Ndị ọrụ na-ebelata ihe na-atụgharị "S" na agba ka ọ bụrụ -SH otu yana njikọ Sulfur.Mgbe ahụ, n'ime ihe ndị thiols nwere -SH dị iche iche na-ekpo ọkụ ma si otú a gbanwee n'ụdị agba mbụ.

E gosipụtara nke a n'okpuru:

Agba-SS-Dye + 2[H] = Agba-SH + HS-Dye

Agba-SH + HS-Dye +[O] = Agba-SS-Dye + H2O

Sulfur na-enye nsonaazụ kacha mma (Tone na-egbuke egbuke) mgbe a na-eji ha na-emepụta ndò ojii, ojii na agba aja aja, mana enweghị ike ịnweta ndò na-acha uhie uhie site na ijiji sulfur.
 
Enwere ike ichikota akụkọ ihe mere eme nke akwa sulfur dị ka n'okpuru:

1. Sulfur agba mbụ ebe emere na 1873 kpo oku hụrụ uzuzu, caustic soda na sọlfọ.O mere na mberede mgbe ụgbọ mmiri mmeghachi omume nwere Na2S na-agbapụta ma jiri uzuzu na-ehichapụ ihe ngwọta na-apụta.Mgbe e mesịrị, ákwà owu na-akpakọrịta na sawdust a metọọrọ ma ghọọ ntụpọ.

2. Ezigbo onye ọsụ ụzọ nke akwa Sulfur bụ vidal bụ onye mepụtara vidal ojii (Aha Sulfur dye) site na ijikọ para-phenylene diamine na Na2S & Sulfur na 1893.

3. Na 1897 Kalischer mepụtara ozugbo Black FF site na kpo oku 2, 4-dinitro-4-dihydroxy diphenylamine na Na-poly sulphide.

4. Na 1896 Gụọ Holliday ẹkenam a nso nke isi awọ, aja aja na nwa Sulfur e ji esiji ákwà site edinam nke Sulphur, alkali sulphides na ọtụtụ organic ogige.
